Diego Biurrun	f75f4194d1	Restructure av_log_missing_feature message Some invocations include a verb in the log message, others do not. Yet av_log_missing_feature expects callers to provide a verb. Change the function to include a verb instead and update the callers accordingly. The result is a more natural function API and correct English in the function invocations.	12 years ago

Michael Niedermayer	5e50a5724b	Revert "removing lowres support" There have been multiple user complaints about loosing this feature while its not clear the 3% speedloss claims where real or fabricated. My own testing indicates no statistically significant speed difference both with mpeg2 and mpeg4, and if at all the code with lowres support is a tiny bit faster than without. This reverts commit `92ef4be4ab`, reversing changes made to `2e07f42957`. Conflicts: cmdutils.c libavcodec/arm/vp8dsp_init_arm.c libavcodec/mpegvideo.c libavcodec/mpegvideo.h libavutil/arm/Makefile Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Ronald S. Bultje	5eec5a79da	jpeg: handle progressive in second field of interlaced. Progressive data is allocated later in decode_sof(), not allocating that data leads to NULL dereferences. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	13 years ago
Michael Niedermayer	70d54392f5	lowres2 support. The new lowres support is limited to decoders where lowres decoding is possible in high quality. I was not able to measure any speed difference, but if one is found the 2-3 lines that might affect speed can be made compile time conditional Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
